WebIn the simplest case a binary phase-shift keyed (BPSK) signal takes the form s.t/ D m.t/cos.!ct/; where !c is the carrier frequency, and m.t/ is a polar binary baseband signal taking on the value 1 for a mark and 1 for a space. Because there are only two different signals, and they differ only by a change of sign, this signalling WebThe word binary represents two bits. M represents a digit that corresponds to the number of conditions, levels, or combinations possible for a given number of binary variables. This is the type of digital modulation technique used for data transmission in which instead of one bit, two or more bits are transmitted at a time.
